Today, Feb. 20, 2010, Sigma announced a new version of its 70-200mm f/2.8 lens--this one with their Optical Stabilizer system, and a new type of low-dispersion glass, as well as a new 85mm f/1.4 EX-DG prime lens. Both lenses will work on FX as well as DX-sized sensors, as well as 35mm film SLRs.

I think the new 85mm will be attractive to many people who want a modern, fast-aperture 85mm lens, but cannot handle the very high cost of manufacturer's offerings in the high-speed 85mm category.

With Nikon and Canon 70200mm f/2.8 stabilized lenses approach the mid-two thousand dollar range at MSRP, I think SIgma will sell a lot of its new 70-200 f/2.8 lens to those who want a stabilized lens, but do not have the $2,300 or so it costs to buy one from the various camera makers.

I like my Nikon 80-200, so i'll stick with that, i don't like how far out the zoom ring is on the new sigma is anyway, the 70-200VR IMO is still too far out.

I'm more curious on the 85mm. I hope it doesn't feel too big. I'm still waiting for Nikon to hopefully make an AF-S 85mm f/1.8 with a rounded diaphragm, just because of cost and size. and the current 85 1.8 is sharper than the 1.4 when stopped down.

I just got the Sigma 18-50 f/2.8 macro... the OS could be useful.
Also just got the Nikon 80-200... maybe I will want the OS on that as well???

I have seen no dates associated with the press releases for any of the new or updated Sigma lenses. However, May and June are big,big camera-buying months, with father's day, graduations, and family vacation times all running together,so if Sigma is smart, they'll try and have these new lenses ready for sale by May. Prices are also still not being mentioned.
